Description

Fixer for combining inline-skate frames with boots or boots chassis}

The present invention relates to a fastener composed of a fixed piece and a backing piece for coupling an inline skate frame to the bottom of a boot or boot chassis (hereinafter referred to as 'boots'), and more specifically, to be fixed in close contact with the bottom of the boot. In the assembling hole formed in the engaging piece of the upper inline skate frame to be provided, a plurality of fixing holes are provided, the outer periphery consisting of the inclined side inserts the fixing piece in close contact with the inner circumferential surface of the assembly hole, the width direction between the frame engaging piece and the boot bottom In-line skate frame to fix the bottom of the boot and the support piece and the fixing piece with bolts and the like while interposing a plate-shaped support piece having an inclined surface so that the fixing position and the engaging angle of the frame coupled to the boot can be easily changed. It is about a coupler.

Roller skates, which are supposed to be designed to get the pleasure of ice skating on the ground when the weather is warm and cannot be skated on ice, are largely divided into quad roller skates and inline skates.

The quad roller skates are generally referred to as roller skates and are attached to the bottom of a skate boot, which is usually made of leather, with a pair of left and right wheels arranged in front and rear in a shape of a rectangular vertex. Since the wheels are attached to the front, rear, left and right, it is easy to balance the body and is suitable for those who are new to roller skating.

The inline skate, also known as Rollerblade, the name of an inline skate manufacturer in the United States, has a large number of wheels arranged in a row in front and rear rows and attached to the bottom of the skate boot. It's hard to balance, but it's fast, and it's capable of performing a variety of tricks.

The inline skates, depending on the purpose of use, for wheels for fast and large speeds for general driving, for aggression for small wheels and for slow speeds, for hockey for hockey, It can run on dirt roads as well as on general roads, and there are various types of off-road use using large wheels reminiscent of tires.

Inline skating as described above is a very good exercise and play equipment that can secure a proper amount of exercise and a considerable interest to students of low momentum due to the spread of computers, etc., and has gained wide popularity from elementary school students to university students. There are also various club activities.

In general, inline skates, as shown in FIG. 1, a boot 11, a boot chassis 12 supporting the boot 11 and acting as an outer shell of the boot, and a frame attached to the bottom of the boot chassis. 13, a plurality of wheels 14 mounted in a row on the frame, and a brake 15 attached to the rear part of the frame.

At this time, the ice skating is attached to the straight metal blade instead of the wheel.

The boots chassis and frame of the inline skate manufactured for general use are usually manufactured by injection molding a synthetic resin having appropriate rigidity, and in the case of a special purpose such as a player, the boots are inserted to be detachable to the boot chassis as described above. In some cases, the frame may be directly coupled to the bottom of a boots having considerable rigidity such as ice skates.

The frame is fixed to the bottom of the boot or boot chassis (hereinafter referred to as the 'boots') with the wheels coupled to support the weight of the person, while being impacted by the collision of the ground with the wheels in progress. When rotating or rotating the boot, the frame and the wheel does not maintain a perpendicular state to the ground, the bending force to separate the coupling portion is strongly applied to the coupling portion of the frame and boots.

Therefore, the frame of the inline skate must be firmly fixed to the bottom of the boot to withstand such external forces.

As shown in Figure 2, the upper portion of the frame 13 is provided with a front and rear two flat coupling pieces (13A), the upper surface of the two coupling pieces in close contact with the bottom of the boot, usually formed on the coupling piece 4 The coupling pieces and the bottom of the boot are brought into close contact with each other through the two through-holes, and the bolts / nuts or rivets are fixed together.

Frame fastening method using four fasteners as described above has a disadvantage in that the productivity takes a lot of work time, so to form one coupling hole in the center of each coupling piece of the frame and use one fixture for each coupling piece A method of combining the frame and the boot chassis has been developed.

However, there is the following problem in the coupling of the frame and the boot through the through-hole fixed to the coupling piece of the frame as described above.

When the frame is damaged and the frame is to be replaced, if the position of the through hole formed in the joint of the damaged frame and the replacement frame is different, the frame cannot be replaced or a new hole, that is, a new coupling hole must be drilled in the bottom of the boot. Will occur.

In particular, in the case of athletes or stunts, it is preferable to replace the frame as needed, but the position of the through-holes for each frame is different, the situation is to replace the boots together instead of replacing only the frame.

In order to improve the conventional method of joining the frame as described above, a plurality of circular or rectangular through-holes are formed on the joining pieces of the frame so that the frames having different positions of the through-holes can be joined to the fixed position joining holes of the boots. However, in this case, there is a problem that a decrease in productivity for forming the plurality of through holes in the engaging piece of the frame is inevitable.

In addition, the coupling method as described above has a problem in that the coupling angle at which the coupling piece upper surface of the frame and the boot bottom are in close contact is fixed.

That is, in the case of the conventional inline skates, the frame is vertically fixed to the bottom surface of the boots that are in close contact with the sole, and the posture of the legs and the frame perpendicular to the ground becomes an ideal state. When skating, the frame is inclined with respect to the ground because it is difficult to take such a posture.

Therefore, in severe cases, there is a problem that a lot of effort is required because the legs must be erected in order to increase the inclination of the frame so that the boots do not touch the ground, and the degree of inline skating technology is immature. There is a problem that becomes large.

The present invention was devised to solve various problems of the conventional method of joining an inline skate frame to a boot bottom. The coupling piece of the frame is separated into two parts of the center part and the rim part, and the rim part is integral to the frame as in the prior art. The center portion is separated into a separate component formed with a plurality of fixing holes for coupling the frame to the boot, and a separate means for adjusting the engagement angle of the frame between the frame coupling piece and the bottom surface of the boot. It is an object of the present invention to provide an in-line skate frame joining device that allows the frame to be coupled to the boots in the intervening state so that various frames can be mounted without replacing the boots, and at the same time, the engaging angle of the frame to the boots can be adjusted. .

The above object of the present invention is achieved by a plate-like fixing piece having a plurality of fixing holes formed on the inner circumferential surface of the assembly hole formed in the frame coupling piece and having a plurality of fixing holes, and a plate-shaped support piece having an inclined surface in the width direction.

Prior to the description of the present invention to match the terms, such as frame-combining piece-assembly, fixing piece-through hole, support piece-combining hole.

The inline skate frame coupler of the present invention is composed of a fixing piece and a half needle piece, the fixing piece is parallel to the upper and lower surfaces, but the side forms an inclined surface, the side is in close contact with the inner circumferential surface of the assembly hole of the frame upper coupling piece to support the frame.

In addition, the fixing piece has a plurality of fixings penetrating the upper and lower surfaces of the fixing piece so as to freely change the engagement position of the fixing piece of the present invention with respect to the fixed coupling hole of the boot bottom through which fixing means such as bolts pass to fix the frame. Balls are formed.

In other words, by properly selecting the fixing hole of the fixing piece corresponding to the fixed coupling hole of the boot bottom, it is possible to easily change the position of the fixing piece fixedly coupled to the boot bottom.

Therefore, there is a technical feature of the present invention that the position of the inline skate frame provided with the assembling hole coupled to the side of the fixing piece can be easily changed together with the fixing piece as necessary.

In addition, the support piece, which is another metal piece constituting the coupler of the present invention, is characterized in that its lower surface is inclined with respect to the upper surface in the width direction, so that its cross section is in the shape of a wedge, and the support piece is coupled to the frame. The frame is coupled to the boot with the gap between the piece and the bottom of the boot.

That is, the angle of engagement of the frame with respect to the boot bag trapping surface is determined by the inclination angle of the support piece.

The details of the purpose and technical constitution according to the present invention, including the effect thereof, will be clearly understood by the following description with reference to the drawings showing preferred embodiments of the present invention.

Figure 3 is a perspective view of an embodiment of the present invention fixed piece, Figure 4 (a) and (b) is a perspective view and a front sectional view of the support piece.

As shown in the drawing, the fixing piece 3 constituting the present invention has an upper surface 3A and a lower surface 3B parallel to each other, and an area of the upper surface 3A is smaller than that of the lower surface 3B. The side surface 3C connecting the inclined surface inclined toward the center of the upper surface from the lower surface to the upper surface.

In the fixing piece 3, a plurality of through holes H penetrating the upper surface 3A and the lower surface 3B are formed perpendicular to the upper and lower surfaces 3A and 3B. These circular through holes (H ') and rectangular through holes (H') are formed together, but may be composed of only one type of through holes of the two types of through holes.

However, in the case of the rectangular through hole (H ') than the circular through hole (H') is more convenient for fine adjustment of the position of the fixed piece, the circular through hole (H ') than the rectangular through hole (H') is the fixed piece It can be more securely fixed in one place, and it is more preferable to have both types of through holes together.

The support piece 4, which is another element constituting the present invention, is in close contact with the bottom surface of the boot, and the outer circumferential shape thereof is preferably similar to the bottom surface of the boot. 4B) is characterized by an inclined surface having an inclination, and in order to use fastening means such as bolts, the support piece 4 passes through the upper and lower surfaces 3A and 3B to coincide with the coupling hole of the boot, but the upper surface 3a. Coupling hole h perpendicular to) is provided.

In addition, the angle θ formed between the top surface 4A and the bottom surface 4B of the support piece 4 is preferably 40 ° or less, which is an engagement angle of the frame with respect to the boot bottom when the angle exceeds 40 °. It is so tilted that excessive load is concentrated on the frame and boot joints, which can strain the feet and legs when inline skating or stopping.

5 is a view showing a coupling piece portion of the frame to which the fixing piece 3 constituting the present invention is coupled.

As shown, in order to be able to use the fixing piece 3, the coupling piece 5A having the same shape as the outer shape of the fixing piece should be provided on the coupling piece 5A on the upper part of the frame 5, and the fixing piece is provided at the upper part of the lower frame. The side surface of the fixing piece is inserted into the assembly hole 5A in the direction to be in close contact with the inner circumferential surface GS of the assembly hole.

Therefore, the inner circumferential surface GS of the assembling hole should also be inclined toward the center of the assembling hole as it goes from top to bottom, and the top surface of the fixing piece is flush with the top surface 5A of the frame coupling piece in a state where the fixing piece is completely in close contact with the assembly hole 5A. It must not protrude on or out of it.

That is, because the fastening means such as bolts are coupled to the boots by the frame that is in close contact with the side of the fastening piece by the force of pulling down the lower surface of the fastening piece, the upper surface of the fastening piece is on the same plane or out of the upper surface 5A of the frame engaging piece. When protruding, the force pulled by the fixing means cannot be transmitted to the frame so that the frame flows, so that the upper surface of the fixing piece must be located below the upper surface of the engaging piece 5A while the fixing piece is engaged with the assembly hole 5A. It should be possible.

As shown in Figure 6 showing the coupling structure of the boot and the frame using the coupling sphere of the present invention consisting of a fixed piece and the support piece, the support piece 4 and the frame coupling piece on the bottom surface (BS) of the boot (B) The upper surface of 5A is in close contact with the fixing piece 3 from the inner bottom surface BS 'of the boot in a state where the fixing piece 3 is tightly inserted into the assembly hole formed in the frame engaging piece 5A. It is a structure that is coupled by the fixing means (L) penetrating the lower surface, and the upper surface and the backing piece (4) of the fixing piece (3) because the upper surface of the fixing piece (3) is located below the upper surface of the frame engaging piece (5A). Space (S) is formed between the lower surface of.

At this time, since the frame 5 is inclined from the outside of the foot to the inward direction I with respect to the boots B perpendicular to the ground, the skewing of the frame against the ground becomes less effective in inline skating, so that the effective skating is performed. This becomes possible.

As described above, the fixing piece constituting the frame coupler of the present invention is to be equipped with a variety of inline skates, in particular, by allowing the various types of frames to be easily mounted with respect to one boot, regardless of the coupling position. It is useful for athletes who have large feet, so that they can continue to use inline skates by replacing only the boots, which has the advantage of reducing the cost of replacing the inline skates.

In addition, the support piece has the advantage that the angle of engagement of the frame in the vertical state to reduce the force applied to the feet and legs at high speeds, while also accelerating the running speed faster to help athletes improve the record In addition to this, it is expected that even beginners can easily learn driving skills.
